SEPARATING-TRAP.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed December 28, 1915. Serial No. 69,019.

To all whom it may concern:

Be it known that 1, JOHN W. NEWMAN, a citizen of the United States ofAmerica, residing at Ridgefield Park, Bergen county, New Jersey haveinvented a new and useful Separating-Trap, of which the following is aspecification.

My invention relates to devices termed separating traps and in thepresent instance, I have shown and described my in vention as applied tosteam and water separation. v

The object of the invention is to permit condensation to be drawn out ofa steam line without allowing the pressure in said steam line to drop.

In the drawings: Figure 1 is a plan view of my invention. Fig.2 is aside elevation thereof. Fig. 3 is a relatively enlarged sectional viewon the line 33 of Fig. 1 showing certain parts in elevation. Figs. 4:and 5 are detail views.

1 represents conventionally a steam chamber wlthin which condensation isliable to occur. The problem is to separate, or draw off, the water ofcondensation without permitting the steam pressure to drop. This Iaccomplish by the following instrumentality :'22 are main supportingblocks upon which is tiltably mounted my improved mechanism whichoperates after the manner of a walking beam. 3 represents the walkingbeam proper which is mounted on the supports 22 in the mannerhereinafter described. i5 are tanks suitably mounted on the walking beam3 at opposite sides of the fulcrum therefor, the fulcrum being solocated relatively to the combined weight of the apparatus carried bythe walking beam, that the end bearing the tank 1 will normallyoverbalance the opposite end carrying the tank 5. The walking beam 3 ismounted directly upon a saddle block 6 (Fig. 3) which has at oppositesides tubular extensions 78 securely fastened thereto. At the ends ofthese tubular extensions are packing boxes 910, respectively. Thesetubular extensions have suitably formed bearings which rest upon thesupporting blocks 22, which latter are formed so as to provide bearingboxes 1l11 which may, if desired, be provided with anti-friction devicesto permit the walking beam 3 to oscillate more freely. These tubularextensions 7-8 operate, in eifect, as hollow trunn na and bl is startthe a i u water connections with the two tanks respectively without theuse of flexible tubing.

I will now describe the piping. A pipe 12 leads down from the chamber tobe drained to a back check-valve 13, thence on through pipe 14: throughthe stufling box 9, and into the chamber 15 within the trunnion 7. Bypreference the inner part of this pipe 14 has a bearing shoulder 16which bears with reasonable snugness against an internal shoulder on thetrunnion shown adjacent thereto. 17 is a spring which serves to keep theshoulder 16 in engagement with the internal shoulder on the trunnion. 18

is an outlet at the inner end of the pipe 14 which opens into thechamber 15. Proceeding from the trunnion 7 and in communication with thechamber 15 is a pipe 19 which leads into the tank 4 and terminates nearthe upper part thereof. 20 is an outlet pipe leading from the bottom ofthe tank 1 across to and into the tank 5 and terminating near the upperpart thereof. 21 is a pipe which leads from the bottom of the tank 5into the trunnion 8 so as to be in communication with the chamber 22thereon. 23 is a pipe which enters the chamber 22 in the same manner asthe pipe 14 enters the chamber 15. This pipe 23 has an opening 24through which water may flow into the pipe 23. The pipe 23 leadsoutwardly through the stufling box 10 and communicates with a dischargepipe 25 in which is located a valve 26 and beyond the valve 26 is acheck-valve 27. The valve 26 is connected in any suitable way as by anarm 28 with part of the tilting mechanism so that when the walking beamstands in the position shown in Fig. 2 the valve 26 will be open,whereas when the walking beam is tilted to the opposite position, thearm 28 will descend and the valve 26 will be shut. Any suitable valveclosing means may be provided, as for example, a gravity closer weight29. 3030 are vents in the upper parts of the tanks l5. 31 is a postwhich limits the descent of the walking beam 5. at one end while 32 is apost which limits the descent of the walking beam at the other end.

Having now described the various parts of the construction, itsoperation will be seen to be as follows: I first block up that end ofthe walking beam supporting the tank 4 so that the opposite end willrest upon the post 32 and the valve will b6 closed, I then open thevents in the tanks until the water of condensation will fill both tanks.I then shut the vents and take out the block, after which the trap willwork automatically as follows: Upon the taking out of the block the tank4 will descend, by reason of the fact that it will then overbalance theopposite end of the tilting mechanism. This movement will open the valve26 whereupon the water in tank 5 will commence to flow out. It ispreferable that the capacity of the pipe should be such that the waterwill not flow out at a more rapid rate than it can flow into the tank 5from the tank 4. Now, as the water flows out of tank 5, it will tend tocreate a partial vacuum which tends to draw the water from the bottom oftank l. So far as there is any pressure in tank 4, this pressure willalso tend to assist in the flow of the water from the tank 4: into thetank 5 through pipe 20, so as to supply the opposite end of the tiltingmechanism, the

beam 5 will tilt back to the position inclicated in Fig. 2 and theemptying process will again take place. By this means, after the trap isonce started, it will automatically tilt to and fro so as toperiodically discharge the water of condensation without allowing thesteam pressure to lower. Obviously the check valves 13 27 may not beemployed in all cases, for example, where there is no tendency to backpressure, but when there is tendency to back pressure such check valvesare desirable. In some cases it may be necessary to use high pressuresteam for forcing the discharge from the trap to a boiler or to anelevated tank which will be understood by those familiar with this art.In such case, the high pressure steam will be admitted at the same timethat the outlet valve is opened and closed when the outlet valve isclosed.

In the preferred construction, such as I have employed with markedsuccess, I have observed the following proportions in the use of tankswith approximately fifteen and a quarter gallons capacity each. Theintroductory pipe let is one inch in diameter, the connecting pipe 20 aninch and a half in diameter, and the discharge pipe 25 a half an inch indiameter. It is also desirable to have the bearing shoulder 16 and itscooperating shoulder, as provided on each of close to the trunnions 78to prevent said pipes from turning, in which event, I provide theholding pedestals 3333.
